We look at the division of 170431 by 65 
We want to figure out the number of times 170431 can be divided by 65.

Going ahead to step 1:
1 divided by 65 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 65

Let's proceed to step 2:
65 can be fit into 17 0 times, resulting in a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 65

Moving on to step 3:
170 divided by 65 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 130 from 170, we get 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 65

Step 4:
65 goes into 404 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtract 390 from 404 to get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 65

Advancing to step 5:
143 divided by 65 is 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 262.0
If we take 130 away from 143, we end up with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 65

On to step 6:
The number 65 fits into 131 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 2622.0
Subtract 130 from 131 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
65 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2622.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 65, we get 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 2622.01
Deduct 65 from 100 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
If we divide 350 by 65, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 2622.015
The remainder is 25 after subtracting 325 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
If we divide 250 by 65, we get 3 and a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 2622.0153
If we take 195 away from 250, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
65 can be fit into 550 8 times, resulting in a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 2622.01538
The remainder is 30 after subtracting 520 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
The number 65 fits into 300 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 2622.015384
If we take 260 away from 300, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
65 can be fit into 400 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 2622.0153846
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
100 divided by 65 is 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 2622.01538461
The remainder is 35 after subtracting 65 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 2622.01538461 with a remainder of 3.5e-08.
